TMS320DM642AZDK6

Digital Signal Processor Dsp Overview

The TMS320DM642AZDK6 is a video and imaging fixed-point digital signal processor based on the C64x+ DSP core. It operates at clock rates of 500, 600, or 720 MHz, delivering up to 5760 MIPS. The architecture features eight independent functional units (two multipliers and six ALUs) supporting VelociTI.2 extensions for parallel processing. On-chip memory includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB configurable L2 RAM/cache. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP0, PCI, and EMIF. The device utilizes a 548-pin BGA package with 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (-500, -600, or -720) required for the target application frequency. Confirm that the ZDK suffix corresponds to the correct 548-pin BGA package with 0.8-mm ball pitch. Ensure compatibility with existing development tools such as Code Composer Studio for software integration.

Digital Signal Processor Dsp Selection Notes

Select the appropriate clock speed variant based on computational requirements. The DM642 supports both little-endian and big-endian modes. Developers must account for peripheral pin multiplexing, as certain interfaces like VP0 share pins with McBSP0 and McASP0 control lines. Verify power supply requirements, noting the 1.2V or 1.4V core voltage depending on the speed grade.

Digital Signal Processor Dsp Part Context

The TMS320DM642 belongs to the TI C6000 DSP platform, specifically designed for high-performance digital media applications. It is code-compatible with other C64x devices. The AZDK6 designation indicates a specific manufacturing lot or revision within the standard production data set for this video-focused processor family.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout are limited due to the age of the component. Consider the TMS320DM643 for similar functionality with potential performance variations, or newer DaVinci processors for updated feature sets, though these may require schematic and software redesigns.
